Wear plate

If you own or manage a business that uses any kind of mechanical equipment, the best way to protect the value of these assets is by equipping them with premium wear plates. This is true whether you are leasing or financing the equipment in question. Because of the high costs that come with equipment and machinery, it’s important to maintain the equipment so that your investment will be a worthwhile one.

No matter how well you protect your equipment, standard wear and tear is a natural occurrence that cannot be prevented. Abrasion will invariably result from the grinding that takes place with the mechanical components inside the machinery. Among the more effective methods of protecting equipment is by using wear plates to provide an additional layer of protection.

What Are Wear Plates?


Wear plates are very hard steel plates that can come in a variety of different thicknesses. These plates are typically welded in areas of machinery and equipment where there is already a significant amount of wear and tear. It’s important to understand that not every machine needs wear plates. However, the presence of wear and tear that’s caused by abrasion may signal that it’s time for you to start using them.

Wear plates are most commonly applied to machines that rotate or slide when they are being used. While wear plates are beneficial because they can help you maximize the life of your machinery, they are also advantageous because they are easy to install and relatively inexpensive when compared to the cost of replacing an entire part. The types of machinery that can be protected with wear plates are used across a wide range of industries, which makes them useful for practically any kind of business.

Primary Applications for Wear Plates

The main types of machines and components that could benefit from wear plates include:

  • Shredders
  • Crushers
  • Casting equipment
  • Equipment for moving heavy earth
  • Aluminum and steel mill equipment

While these are the primary machines that wear plates are used with, some additional applications for steel plates include:

  • Scrapers
  • Chippers
  • Wear blades
  • Bucket scrapers
  • Wear rings and segments
  • Punch press applications
  • Various mining tool

No matter the application you use a wear plate for, it should be able to extend the life of the machinery in question. When you’re selecting wear plates for your machinery, keep in mind that the hardness of the plate can make a significant difference in how the plate is being used. While harder and more durable plates will last longer, there are some parts that require a softer material that will wear out before the main surface does. As such, it’s important that you take the type of machine into account when assessing which wear plate you should use.

Wear plates are utilized by a wide variety of companies. If the equipment that your company uses is outfitted with components that come into contact with corrosive or abrasive materials, wear plates can be beneficial. Wear plates are commonly used within aluminum mills, steel mills, pipe mills, military facilities, mining facilities, and chemical companies.

Different Types of Wear Plates

There are three primary types of wear plates that you should know about, which include ones that are made from minerals, ones that are made from ceramic liners, and low-friction UHMWPE options. Along with the three primary types of wear plates, each wear plate requires some base parts with softer materials that allow the plates to reach desired efficiency. Before you decide which of the three wear plates is right for you, it’s important that you understand the benefits of each.

Ceramic Liner Plates
Ceramic Liner Plates

Wear plates that are comprised of ceramic liners can lessen the amount of sliding abrasion that occurs while also limiting damage caused by moderate and heavy impacts. Because the surface of these liners is smooth, friction will be effectively reduced when the components within the machinery are sliding. These sliders are ideal for very specific uses.

Mineral Plates

what is wear plate

The exact hardness of the base material that you choose for the plate determines what the coating will be. The right coating will allow the plate to function at peak capacity. Harder wear plates typically provide better wear resistance. There are many types of mineral coatings that you can select from when choosing a wear plate, which include:

  • Chromium carbide
  • Mild steel
  • Weathering steel
  • Grade 50B steel
  • A variety of additional hard metals

Any of these coatings will serve you well if you would prefer to use a mineral plate for your machinery.

Low-Friction UHMWPE

ULTRA-HIGH-MOLECULAR-WEIGHT-POLYETHYLENE
The UHMWPE in low-friction UHMWPE stands for ultra high molecular weight polyethylene, which is a material that is molded into rod and sheet shapes before being used as wear plates. Once the material has been molded into a rod or sheet, it will be bolted directly to the machinery. Despite the fact that these wear plates are highly effective, they are typically used for specific applications. Low-friction UHMWPE plates are commonly applied to gears, canning lines, conveyor flights, skid plates, and sprockets. The main benefits of using low-friction UHMWPE include:

  • Non-stick
  • Self-lubricating
  • Resistant to impact
  • Resistant to friction
  • Resistant to a wide range of chemical

These wear plates are designed to last for a very long time no matter which type of machine you pair them with.

While wear plates aren’t always essential, they can make it easier for you to maintain the quality of the high-end equipment and machinery that your business uses. Now that you know about the various types of wear plates, it should be easier to select ones that would work well in your business.

In some cases, we can modify your equipment to incorporate these liner plates when not in the original equipment design. If your equipment has lost some efficiency or does not hold the same tolerances as new, inspect the worn parts. There could be an easy and cost effective fix to the problem.
